Abstract

The nuclear warhead detecting technology based on a template with γ spectrum of Plutonium is an important verification means in the deepirreversible nuclear disarmament. In order to obtain the γray spectra， γray transportation processing for the hypothesis nuclear warhead model has been simulated. In a possible nuclear disarmament verification case， the template matching algorithm based on the relative counts of the explored γ spectrum of Plutonium in subenergy region is built up， and the template technology of nuclear warhead composed of element matching and structure matching is established. This method could eliminate the effect of the error caused by the detecting distance and time.
